What should I do?

Jenna

I was on the Depo injections for 2 years, had my last one September 2018. It ran out December 2018 and I had my first period after Depo October 2019. Had another period in November and was due again end of December however it never came. I’m now 8 days late but multiple pregnancy tests have come up negative. I was always clockwork regular pre-birth control. Should I go to the doctor? Wait and do more home tests?
